Abstract
A method for the estimation of oil recovery factor in a foam flooded hydrocarbon reservoir. The hydrocarbon reservoir is divided into three sweep sub-zones, with sweep efficiency and displacement efficiency for each zone being estimated. The oil recovery factor is determined as a function of porous volume injected, based on the sweep efficiency and displacement efficiency.
